IB SL Biology Lab Molecular Biology: Transformation and Electrophoresis Christina Qi 2/16/07 Aim: How can a plasmid be engineered to include a foreign piece of DNA and how does gel electrophoresis separate DNA molecules present in a mixture? Hypothesis: If the pGLO plasmid is inserted into competent Escherichia coli cells‚ then the transformed bacteria will be resistant to ampicillin and will glow green under UV light. If samples of DNA are cut using certain restriction

Beetroot Cells with High temperatures and low pH solutions Friday 15th March 2013 Abstract (50) The aim of this investigation was to study the effects of temperature and a low pH solution on beetroot cells. Introduction (200) The general belief amongst our group members was: an increase in temperature will damage the permeability of the plasma membrane. Also‚ the heat will break away the permeability. If the pH solution is 7 or greater there will be no change but the lower the pH the more proteins

IB CASE STUDY * CHAPTER 2 [OBJ 2] Successful companies have insightful strategies‚ great supply chains and sharp financial systems. Ultimately‚ though‚ success is a function of the people who start and sustain the company. The challenge of putting the right person into the right job in the right place at the right time for the right compensation takes us to the front lines of international business. One can evaluate HRM from many perspectives. Two reasons motivate an executive perspective

Since I am a biology major‚ I thought this would be the perfect opportunity to compare two prospective courses I could be taking next semester. One of these classes‚ specifically‚ is Biology 121. Biology 121 is the first half of a two-semester introduction over the major components of Biology. The course discusses molecular and cellular biology‚ genetics‚ and evolution. The

What is Life Life is defined as a characteristic that distinguishes that have signaling and self sustaining processes from those that don’t. If an organism can perform certain functions such as movement‚ respiration‚ sensitivity‚ growth‚ reproduction‚ excretion‚ and nutrition‚ it is classified as a living organism. Life began from the basic building block of all living things‚ called cells. All organisms derived from single celled organisms. Cells are the basic building blocks of life and are

With the evolution of animals living on land from animals living in the water‚ many changes needed to be made in order for survival. Each problem that these organisms may have experienced in the past has been dealt with a solution of some manner. One of the main problems was water storage. Because organisms in an aquatic environment are surrounded by water‚ they do no experience problems with water storage‚ but without an aquatic environment there are bound to be problems. The land organisms need

In order to become fully aware of the biology associated with social work‚ there are a number of things I need to learn more about. First‚ I would need to become familiar with the DSM-V‚ which is the most common source used to diagnose mental health conditions. My mother has a copy of the previous version and it would be great to educate myself on even more conditions than we discussed in this class prior to entering the workforce. Also‚ I feel it would be important to dive deeper into the study
